My battery couldn't start the car for the first time. I have the system installed for about 7 months now.

It was 65 degrees two days ago, drove fine to and from work. 35 degrees yesterday, didn't really drive that much - only to pick up take out (down the block) and to the gym (~5 miles each way), cranked fine.

This morning, I couldn't start the car. Around ~27-29 degrees. The battery had enough juice to lock/unlock the car and turn on all the electronics. It would only crank once or twice and then die. After several more attempts, it wouldn't crank at all. I turned off the heater/AC, seat warmer, ESC, and anything else with an off button; still wouldn't crank. Had to ask my buddy come and jump my car - started up fine instantly after attaching the jumper cables.
